Low-Noise, Low-Dropout,
150mA Linear Regulators in SOT23
_______________General Description
____________________________Features
The MAX8867/MAX8868 low-noise, low-dropout linear
regulators operate from a 2.5V to 6.5V input and deliver
up to 150mA. Typical output noise for these devices is
ꢀ Low Output Noise: 30µV
RMS
ꢀ Low 55mV Dropout at 50mA Output
(165mV at 150mA output)
just 30µV
, and typical dropout is only 165mV at
RMS
150mA. The output voltage is preset to voltages in the
range of 2.5V to 5.0V, in 100mV increments. The
MAX8867 and MAX8868 are pin-compatible with the
MAX8863 and MAX8864, except for the BP pin.
ꢀ Low 85µA No-Load Supply Current
ꢀ Low 100µA Operating Supply Current
(Even In Dropout)
Designed with an internal P-channel MOSFET pass tran-
sistor, the MAX8867/MAX8868 maintain a low 100µA
supply current, independent of the load current and
dropout voltage. Other features include a 10nA logic-
controlled shutdown mode, short-circuit and thermal-
shutdown protection, and reverse battery protection.
The MAX8868 also includes an auto-discharge function,
which actively discharges the output voltage to ground
when the device is placed in shutdown. Both devices
come in regular and thin 5-pin SOT23 packages.

Figure 1. Functional Diagram
The 1.25V bandgap reference is connected to the error
amplifier’s inverting input. The error amplifier compares
this reference with the feedback voltage and amplifies
the difference. If the feedback voltage is lower than the
reference voltage, the pass-transistor gate is pulled
lower, which allows more current to pass to the output
and increases the output voltage. If the feedback volt-
age is too high, the pass-transistor gate is pulled up,
allowing less current to pass to the output. The output
voltage is fed back through an internal resistor voltage
divider connected to the OUT pin.
_______________Detailed Description
The MAX8867/MAX8868 are low-noise, low-dropout,
low-quiescent-current linear regulators designed pri-
marily for battery-powered applications. The parts are
available with preset output voltages varying from 2.5V
to 5.0V in 100mV increments. These devices can sup-
ply loads up to 150mA. As illustrated in Figure 1, the
MAX8867/MAX8868 consist of a 1.25V reference, error
amplifier, P-channel pass transistor, and internal feed-
back voltage divider.

Operating Region and Power Dissipation
The MAX8867/MAX8868’s maximum power dissipation
depends on the thermal resistance of the case and cir-
cuit board, the temperature difference between the die
junction and ambient air, and the rate of air flow. The
reduces noise at the output. Additional blocks include a
current limiter, reverse battery protection, thermal sen-
sor, and shutdown logic. The MAX8868 also includes
an auto-discharge function, which actively discharges
the output voltage to ground when the device is placed
in shutdown mode.

Output Voltage
The MAX8867/MAX8868 are supplied with factory-set
output voltages from 2.5V to 5V, in 100mV increments.
Except for the MAX886 E_K29 and the MAX886 E_K32
(which have an output voltage preset at 2.84V and
3.15V, respectively), the two-digit suffix allows the cus-
tomer to choose the output voltage in 100mV increments.
For example, the MAX8867EUK33 has a preset output
voltage of 3.3V. (see Expanded Ordering Information).

The GND pin of the MAX8867/MAX8868 performs the
dual function of providing an electrical connection to
ground and channeling heat away. Connect the GND
pin to ground using a large pad or ground plane.
Internal P-Channel Pass Transistor
The MAX8867/MAX8868 feature a 1.1 typical P-chan-
nel MOSFET pass transistor. This provides several
advantages over similar designs using PNP pass tran-
sistors, including longer battery life. The P-channel
MOSFET requires no base drive, which reduces quies-
cent current considerably. PNP-based regulators waste
considerable current in dropout when the pass transis-
tor saturates. They also use high base-drive currents
under large loads. The MAX8867/MAX8868 do not suf-
fer from these problems and consume only 100µA of
quiescent current whether in dropout, light-load, or
heavy-load applications (see the Typical Operating
Characteristics).
Reverse Battery Protection
The MAX8867/MAX8868 have a unique protection
scheme that limits the reverse supply current to 1mA
when either V or V
falls below ground. Their cir-
SHDN
IN
cuitry monitors the polarity of these two pins and dis-
connects the internal circuitry and parasitic diodes
when the battery is reversed. This feature prevents
device damage.
Noise Reduction
An external 0.01µF bypass capacitor at BP, in conjunction
with an internal 200k resistor, creates an 80Hz lowpass
filter for noise reduction. The MAX8867/MAX8868 exhibit
of output voltage noise with C
= 10µF. Start-up time is minimized by a
power-on circuit that pre-charges the bypass capacitor.
The Typical Operating Characteristics show graphs of
Noise vs. BP Capacitance, Noise vs. Load Current, and
Output Noise Spectral Density.
Current Limit
The MAX8867/MAX8868 include a current limiter, which
monitors and controls the pass transistor’s gate voltage,
limiting the output current to 390mA. For design purposes,
consider the current limit to be 160mA minimum to 500mA
maximum. The output can be shorted to ground for an
indefinite amount of time without damaging the part.

Thermal-Overload Protection
Thermal-overload protection limits total power dissipa-

Capacitor Selection and Regulator Stability
Normally, use a 1µF capacitor on the MAX8867/
MAX8868’s input and a 1µF to 10µF capacitor on the
output. Larger input capacitor values and lower ESRs
provide better supply-noise rejection and line-transient
response. Reduce noise and improve load-transient
response, stability, and power-supply rejection by
using large output capacitors. For stable operation over
the full temperature range and with load currents up to
150mA, a minimum of 1µF is recommended. Note that
some ceramic dielectrics exhibit large capacitance and
ESR variation with temperature. With dielectrics such as
perature exceeds T = +170°C, the thermal sensor
J
signals the shutdown logic, turning off the pass transis-
tor and allowing the IC to cool. The thermal sensor will
turn the pass transistor on again after the IC’s junction
temperature cools by 20°C, resulting in a pulsed output
during continuous thermal-overload conditions.
Thermal-overload protection is designed to protect the
MAX8867/MAX8868 in the event of fault conditions. For
continual operation, do not exceed the absolute maxi-
mum junction-temperature rating of T = +150°C.

more to ensure stability at temperatures below -10°C.
With X7R or X5R dielectrics, 1µF should be sufficient at
all operating temperatures. Also, for high-ESR tantalum
capacitors, 2.2µF or more may be needed to maintain
ESR in the stable region. A graph of the Region of

responses.
Load-Transient Considerations
The MAX8867/MAX8868 load-transient response
graphs (see Typical Operating Characteristics) show
two components of the output response: a DC shift from
the output impedance due to the load current change,
and the transient response. A typical transient for a
step change in the load current from 0mA to 50mA is
12mV. Increasing the output capacitor’s value and
decreasing the ESR attenuates the overshoot.
Stable C
ESR vs. Load Current is shown in the
OUT
Typical Operating Characteristics.
Use a 0.01µF bypass capacitor at BP for low output volt-
age noise. Increasing the capacitance will slightly
decrease the output noise, but increase the start-up time.
Values above 0.1µF provide no performance advantage
and are not recommended (see Shutdown Exit Delay
graph in the Typical Operating Characteristics).
Input-Output (Dropout) Voltage
A regulator’s minimum input-output voltage differential
(or dropout voltage) determines the lowest usable sup-
ply voltage. In battery-powered systems, this will deter-
mine the useful end-of-life battery voltage. Because the
MAX8867/MAX8868 use a P-channel MOSFET pass
transistor, their dropout voltage is a function of drain-to-
PSRR and Operation from
Sources Other than Batteries
The MAX8867/MAX8868 are designed to deliver low
dropout voltages and low quiescent currents in battery-
powered systems. Power-supply rejection is 63dB at
low frequencies and rolls off above 10kHz. See the
Power-Supply Rejection Ratio Frequency graph in the
Typical Operating Characteristics.

) multiplied by the load

current (see Typical Operating Characteristics).
When operating from sources other than batteries,
improved supply-noise rejection and transient response
can be achieved by increasing the values of the input
and output bypass capacitors, and through passive filter-
ing techniques. The Typical Operating Characteristics
